Overview
Finasteride tablets are used for hair loss in men (androgenetic alopecia), to help improve hair growth and hair count over time. Finasteride is also used for benign prostatic hyperplasia (BPH) in men with an enlarged prostate to improve urinary symptoms by reducing prostate size, and may delay the need for surgery. Finasteride is only available as a prescription medicine.
In male-pattern hair loss, a hormone called DHT (dihydrotestosterone) causes hair to become shorter and finer and eventually stop growing in the affected area. DHT also causes the prostate to grow larger. Finasteride works by reducing the amount of DHT available by blocking an enzyme called 5α-reductase, which converts testosterone into DHT. Lower levels of DHT help improve hair growth in male pattern hair loss and reduce symptoms of BPH. Finasteride is from a class of medicines called 5α-reductase inhibitors.
Finasteride 5mg tablets are used to treat symptomatic benign prostatic hyperplasia (BPH) in men, and finasteride 1mg tablets are used to treat male pattern hair loss in men.
Finasteride’s first FDA approval was under the brand name Proscar (finasteride 5mg tablets) on June 19, 1992, for benign prostatic hyperplasia (BPH) in men with an enlarged prostate. Propecia (finasteride 1 mg tablets) became FDA-approved for male pattern hair loss (androgenetic alopecia) in men on December 19, 1997. Finasteride is now available as a generic medicine.
Topical finasteride for hair loss has been tested in clinical trials for men with male pattern hair loss, with results showing it to have a similar effect of improving hair count as oral finasteride tablets. The study used a topical solution of finasteride 0.25% w/w (concentration of 2.275 mg/mL) and was a randomized, double‐blind, double-dummy, parallel‐group, 24‐week study. Topical finasteride is not an FDA-approved medicine.
